• China's War Chest of Rare Earth Patents Give an Insight into Total Domination of the Industry

    China is strengthening its grip on the rare earths supply chain and could use its dominant position as a bargaining chip in its trade war with the U.S. China has been investing heavily on facilities to do the bulk of the dirty and environmentally damaging mining and ore processing work for the world, systematically turning its know-how and methodologies into patents that could give it a competitive edge against its rivals. As of October, China had filed for 25,911 patents on all the rare earth elements, far ahead of 9,810 by the US, 13,920 by Japan and 7,280 by the European Union since 1950 when the first U.S. filing was made.

  • Gallium: China Tightens Grip on Wonder Metal

    Did you know that a 5G base station can be squeezed into a casing the size of a shoebox? It’s thanks to gallium, a soft, bluish metal that makes it possible. The chipsets that generate powerful bursts of high frequency radio waves are not made with silicon, but gallium nitride. Gallium is one of the 35 technology-critical elements listed by the U.S. government as a national security concern. Like rare earths, the global supply of gallium is under Chinese control. China produced 390 tons of raw gallium last year, or more than 95 percent of the world output, according to the United States Geological Survey.

  • Q&A: How Ridgecrest Earthquakes Helped Scientists with ShakeAlert

    U.S. Geological Survey geophysicist Sarah Minson was in the thick of efforts to develop an earthquake warning system in California when a series of major temblors struck the sparsely populated community of Ridgecrest in the Mojave Desert this summer. The largest, a magnitude 7.1 quake on July 5, was the biggest to hit the state in decades. The Mercury News asked her about her work — and how this month’s big quakes is helping scientists refine California’s fledgling earthquake alert system.

  • What If a Hurricane Pushed a Surge up an Already High Mississippi River? No One Is Certain.

    The Mississippi River has always been the lifeblood of New Orleans. It’s the reason for the city’s existence, and an awe-inspiring if sometimes forgotten feature of its landscape. One thing it hasn’t been, at least in recent memory, is a threat. That is, until this month, when wary residents caught a glimpse of the old Mississippi, a face of the river that’s been hidden since it was almost completely caged by man nearly a century ago. The compliant river had become a beast scaling its walls.

  • Tackling Emerging Cyber-Social Threats

    DoD has awarded a $2.4 million grant to researchers to support the development of research infrastructure to assess social media and blogs in real time and respond to the growing weaponization of online discourse in influencing peacekeeping, and tactical, operational, and strategic operations.

  • Assessing Handheld Explosives Trace Detectors

    Individuals who carry explosives or have been involved in bomb making are likely to be contaminated with trace explosives, microscopic particles invisible to the naked eye. Without the right equipment, detecting trace explosives can be challenging for responders and security personnel. Handheld explosives trace detectors (ETDs) can be used to complement bomb-sniffing canines, which are still the gold standard in trace explosives detection. These detectors can be used to find trace explosives on individuals, hopefully preventing a dangerous incident.

  • Innovative ways to repair and construct bridges, roadways

    A 2016 American Society of Civil Engineers Infrastructure assessment reported that more than 9 percent of the nation’s bridges are considered structurally deficient and 1 out of every 5 miles of highway pavement is in poor condition. Researchers will develop innovative techniques to repair and construct bridges and roadways through a new U.S. Department of Transportation-funded research center.

  • Dangerous Heat Wave Is Building in the Central and Eastern U.S.

    The National Weather Service said Thursday that an upper-level ridge is building over the southeastern U.S., setting the stage for what will be a miserably hot and humid weekend for millions of Americans. Heat advisories and warnings affect 154 million Americans. In many major population centers, the heat index  is forecast to peak around 110 degrees between Friday and Sunday.

  • New Sensor Improves Earthquake Response Efforts

    The recent massive southern California earthquakes shut down Ridgecrest Regional Hospital throughout the 4 July holiday weekend while the tiny town of Ridgecrest assessed the damages. Researchers developed a new optical sensor which could speed up the time it takes to evaluate whether critical buildings like these are safe to occupy shortly after a major earthquake.

  • Warming Climate Intensifies Summer Drought in Parts of U.S.

    Climate change is amplifying the intensity and likelihood of heatwaves during severe droughts in the southern plains and southwest United States, according to a new study. The findings raise the idea of a self-reinforcing climate loop: as a region’s climate becomes more arid due to climate change, droughts become hotter, further reducing soil moisture.

  • Raising Tough Questions about Retreat from Rising Seas

    As the global thermostat climbs and polar ice melts, the oceans are swelling and swallowing up coastlines. By some calculations, rising seas could displace 13 million Americans by 2100. While some communities are attempting to adapt in place with elevated buildings and seawalls to divert water, relocation appears inevitable for many.

  • Preventing West Antarctic Ice Collapse by Snowing Ocean Water onto It

    The ice sheet covering West Antarctica is at risk of sliding off into the ocean. The slow, yet inexorable loss of West Antarctic ice is likely to continue even after climate warming is stabilized. A collapse will raise sea levels worldwide by more than three meters. Researchers are now scrutinizing a daring way of stabilizing the ice sheet: Generating trillions of tons of additional snowfall by pumping ocean water onto the glaciers and distributing it with snow canons.

  • Helping first responders deal with dirty bombs

    If a radiological dispersal device (RDD), or “dirty bomb,” ever explodes in the United States, emergency crews may be better prepared because researchers have developed a new simulator, which show first responders what an optimal response to an RDD would look like.

  • Fighting anthrax by removing the bacterium’s armor

    Anthrax is a deadly and highly resilient disease, caused by the spore-forming bacterium Bacillus anthracis. Historically, it was a major cause of death in humans and cattle. has shown that removing the armor of the bacterium that causes anthrax slows its growth and negatively affects its ability to cause disease.

  • Predicting flood duration

    The duration of floods can be determined by river flow, precipitation and atmospheric blocking. Researchers now offer a novel physically based Bayesian network model for inference and prediction of flood duration. The model also accurately examines the timescales of flooding.
